Time : 08:40-09:05
Auric Bhattacharya have completed his Masters in Oral and Maxillofacial Surgery from India. He has worked as Assistant Professor in Manipal University College Malaysia from last four years. He has been conferred fellowship from International Congress of Oral Implantologists in 2017. He also been awarded MFDS from Royal College of Surgeons and Physicians, Glasgow.
Introduction/Background: Tooth extractions are commonly done with conventional forceps. Recent advances like physics forceps help in atraumatic extractions by preserving the buccal plate having less pain and better gingival healing. The buccal beak of the physics forceps is a plastic covered bumper which prevents reflection of buccal gingiva and buccal plate fracture. This is the first such comparison study to not only measure gingival healing post-operatively, but also to perform the comparison exclusively in mandibular molar region.
Objective: To compare the efficacy of physics forceps and conventional forceps in extraction of mandibular molars by randomly dividing the patients in two groups. The efficacy is determined by comparing the success of extraction, relative pain score, incidence of alveolar fracture, patient satisfaction and soft tissue healing on 3rd post-operative day.
Methodology: Patients who were indicated for extraction were included in the study. They were divided into two groups of 10 by double blinded randomization. Local anaesthesia was administered, and the extraction was carried out using either physics or conventional forceps. Post extraction, the pain score was assessed using the VAS. Along with these, the gingival healing, success of extraction and alveolar plate fracture was assessed by the subject expert on the 3rd day post-operative day.
Results: The median score and interquartile range for both the groups was calculated. P value was determined using the Mann-Whitney U test for all parameters except alveolar plate fracture. Patients in the physics forceps group had significantly better results (P value< 0.05) for each of the parameters except success of extraction and alveolar bone fracture.
Conclusion & Recommendation: We can conclude that physics forceps has significant advantages like better patient satisfaction, VAS score and gingival healing. The bumper on the buccal plate prevents the fracture of buccal plate and results in superior rehabilitation. Physics forceps can replace the normal forceps for extraction of mandibular molars which are not grossly decayed. However, a larger sample size will help us in determining more conclusive results.

Wan Zaripah Wan Bakar is an academician and clinical specialist (Prosthodontist) at Universiti Sains Malaysia. She has done several researches related to dentistry in area of restorative/prosthodontics, endodontics and dental material. She also involved in education studies and staff improvement especially about interactive lecture. Once a while she was invited to give a speech at local and international conferences or webinars.
Dental material, conventional GIC (cGIC) is well liked because it is easy to use, anti-cariogenic due to fluorides release and good bond to tooth structure. Anyway, the current available cGIC in the market has limited use due to its relatively inferior mechanical, physical and aesthetics properties. Recently, a novel version of improved cGIC has been successfully produced by Malaysian researcher with a prototype named GiZiDent. It was fabricated from novel nano ZrO2 -SiO2 -HA powder that was produced using one-pot sol-gel synthesis technique. The fabrication was by incorporating nano ZrO2 -SiO2 -HA compound with special technique and specific ratios into conventional GIC which produced GIC -nano ZrO 2 -SiO2 -HA or the trade name as: GiZiDent.
Characterization studies using SEM dot mapping, TEM micrograph and XRD show that the particles in the powder were homogenously dispersed throughout this invention of GIC with some degree of molecular interaction. The mechanical properties such as Vickers hardness, flexural and compressive strength were enhanced achieving better than the level of ISO standard and the surface roughness profile were identical to cGIC This enhanced cGIC exhibited a significantly lower water sorption but higher solubility than cGIC and it also exhibited a significant color stability together with fluoride release improvement It show significantly lower cytotoxicity than cGIC after 72h. GiZiDent with all the improvement can be used in wider scope as a restorative dental material at high stress bearing areas, for restoration of both deciduous and permanent dentition, as core build-up, aesthetics anterior restoration and stronger Atraumatic Restorative Treatment material. This will open more option and better material for dentistry in future.

Title: Comparing the effect of onion juice and ozonol (Zinc Oxide) in temporarily relieving toothache
Time : 09:30-09:55
Mehdi Jafari-Oori is an Assistant Professor at Atherosclerosis Research Center, Faculty of Nursing, Baqiyatallah University of Medical Sciences. His research interest mainly focuses on nursing, geriatric.
This study aims to assess the onion juice effect on toothache compared to ozonol. This randomized control trial study was conducted at Ardabil, Iran in June 2016. The patients with tooth problems who referred to dentistry were selected and allocated randomly in two groups. Our sample size was 60 subjects and each group had 30 patients with a toothache. For one group cotton wool soaked in onion juice was used for a few minutes between the damaged tooth and the second group ozonol was applied. A 10-point scale of pain intensity from zero to 10 was used. Our study ethical cod was approved in Ardabil University of Medical Sciences (AUMS) with ethical cod number 9412 in March 2016. The mean and standard deviation (SD) of the severity of toothache in the onion group at before, and 15, 30, 45 and 60 minutes after intervention were 9.06(1.25), 5.53(1.83), 3.83(2.02), 2.63(2.15) and 1.73(2.08) respectively. Also, the mean and standard deviation (SD) of the severity of toothache in ozonol group at before and 15, 30, 45 and 60 minutes after intervention were 8.93(0.98) and 6.33(1.56), 4.63(1.42), 3.33(1.70) and 2.23(1.50) respectively. The severity of toothache in both onion and ozonol groups were significantly reduced over time (p< 0.001). The rate of pain reduction in the onion group was greater than in the ozonol group. Onions are more available and patients with toothache problems can easily use them to temporarily relieve their toothache until they are examined by a dentist at the appropriate time.

Introduction: Preterm births are the major concern in developing as well as developed world. The deleterious effect associated with preterm births range from infant mortality to lifelong morbidity, causing enormous social and economic burden on the society. Although many studies have related preterm births with periodontal disease, the conclusion remains inconsistent. Thus, this study aimed to determine association between maternal periodontal disease and preterm babies.
Methodology: It was a cross sectional analytical study design. Data was collected from 400 pregnant ladies who came to Khyber teaching hospital for delivery. An interview-based questionnaire was used to having questions regarding oral hygiene habits, OHI index, gingival index, extent and severity index. An SPSS 16 software was used to analyze data with 95% confidence intervals and statistical significance set at P<0.05.
Results: Mean age of the subjects was 25.8 SD ±4.9. Nearly half of the pregnant ladies (48%) had poor oral hygiene. The difference of OHI between the two groups was statistically significant. Majority of the pregnant ladies (58%) presented with moderate gingivitis and the difference between the two groups came out to be statistically significant. Many pregnant ladies presented with generalized periodontitis (88%), however the difference between the two groups was not statistically significant. Severity index revealed that nearly (68%) women suffered moderate periodontitis and the difference came out to be statistically significant.
Conclusion: Within the scope and limitations of this study it can be concluded that the studied pregnant ladies suffered from poor oral hygiene as well as varying degree of periodontal disease that may would have been a factor in leading to preterm births.
